Predict the formulas of titanium hydride and titanium carbide formed by saturating the titanium latt — Solid State Chemistry Question
Question
Predict the formulas of titanium hydride and titanium carbide formed by saturating the titanium lattice with either 'foreign' element.
Answer: B
💡 Solution & Explanation
An FCC unit cell has 4 lattice points (Ti atoms). It has 4 octahedral holes and 8 tetrahedral holes. Fully filling tetrahedral holes with H gives Ti4H8 = TiH2. Fully filling octahedral holes with C gives Ti4C4 = TiC.
